In topology, "tautness" refers to a property of a mapping between two topological spaces, specifically in the context of a topological space being a **taut space**. A topological space is characterized as a taut space if it has certain conditions related to continuous mappings, particularly concerning their compactness and how they relate to other properties like being perfect, locally compact, or having specific kinds of bases.
